To all whom it may concern:

Be it known that l, CLINTON Goren, a citizen of the United States, residing at Muncy, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in PipeCouphugs; and I do hereby declare the following to be a full. clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pipe couplings or unions for connecting sections of piping at different angles, and is an improvement over that type of coupling in which contiguous pipe-sections are provided with flanges having inclined faces and bolted or clamped togetl'ier with an interposed ga ket or gaskets. Such couplings as heretofore constructed depend upon the clamping bolts for holding the pipes in registration or alinement. and in adjusting at diil'erent angles there is apt to be more or less derangement of the flanges and impertect registration of i6 bores oi the pipe, with consequent liability of leakage and also contraction of the fiuid passage. Another point oi" weakness is the impossibility of holding the gasket oetwecn the faces of the flanges under high pressure, it being a well known fact that pressure will displace the gasket or force it between the bolts.

The object of this invention is to provide a practical and etlicient coupling oi t ie above stated character, in which permanent registration of the pipes will be maintained the bolts than to thus obviating the Such ob ect 15 atwithoutfurther duty of clamp the parts tog ther. diliiculties mentioned.

'tained by means substantiallj as illustrai'wl in the accompanying drawings. which are to be taken as a part ot'this specification and in which:

An explai ation of the illustrated coupling is as follows: The ends of adjacent pipe couplings A and B are provided with pipe flanges C and D, on the inner t'aces oi which are central tubular bosses E and F.

Said bosses have their ends cut obliquely gasket l; the male projection G fitting revolubly in said recess and abutting against said gasket. Thus the flanges may be turned to permit relative angular adjustment of the bosses one on the other, which adjustment will vary the aof the pipe flanges from coincidence or true alinement to various angles wi h the limit allowed by the degree of inclination of the faces of the bosses, thus determining the angle at which the pipe sections may be coupled. Bolts J are provided for clampin the flanges together. and a series of bolt holes K therefor in each flange, those in the two flanges arranged to register, so that the flanges can be turned elatively to the other and secured toeeh at angles determined by the spacing t he bolt holes. By this construction, peri registration of the bores of the pipe is naimained at all times, both in making ad- 'ustments and when the pipes are coupled 'll'lltfl' in alinement or at any angle within 'l limits allowed; and the gasket being d in the recess ll is secured against dislcen nt or forcing out by compression, bots being relieved of all duty except 0 clamp the parts together. Thus the liability ot' leakziige is prevented and a permanent steam tight joint assured.

Qt pair of coupling bolts would answer under many conditions. though a tall complement oi bolts. according to the number of bolt holes, would ordinarily be preteroble especially where the pipes are used for tluid pressure or where the coupling is apt to be subjected to torsional. shearing or other strains. in view oi the di'tl'erent angular adjustment permitted, the bolt holes should of course be of larger diameter than the bolts and either wedge-shaped washers or washers L having convex or rounded bases may be interposed between the boltheads and fastening nuts to provide fiat bearing surfaces for the latter at all times.

Other clamping means than bolts may be employed if desired.

\Vhat I claim as my invention and desire to secure by Letters Patent is:

A pipe-coupling comprising a pair of pipe-flanges, each pipe being provided on its outer face With an outstanding boss, the terminating face of each boss being oblique to its axis, the oblique face of one boss being provided with an annular recess, a gasket seated therein and the oblique face of the other boss having a round projection fitting revolubly in said recess and against said I gasket, the rotation of either flange relative to the other constituting an angular adjustment Which varies the axes of the pipeflanges, and means for clamping said pipefianges together.

In testimony whereof I afiiX my signature, in presence of two Witnesses.
